— Woodrow Wilson
Context: If every nation is going to be our rival, if every nation is going to dislike and distrust us, and that will be the case, because having trusted us beyond measure the reaction will occur beyond measure (as it stands now they trust us they look to us, they long that we shall undertake anything for their assistance rather than that any other nation should undertake it)— if we say, "No, we are in this world to live by ourselves, and get what we can out of it by any selfish processes," then the reaction will change the whole heart and attitude of the world toward this great, free, justice-loving people, and after you have changed the attitude of the world, what have you produced? Peace? Why, my fellow citizens, is there any man here or any woman, let me say is there any child here, who does not know that the seed of war in the modern world is industrial and commercial rivalry? The real reason that the war that we have just finished took place was that Germany was afraid her commercial rivals were going to get the better of her, and' the reason why some nations went into the war against Germany was that they thought Germany would get the commercial advantage of them. The seed of the jealousy, the seed of the deep-seated hatred was hot, successful commercial and industrial rivalry.
